- Description
- SCOPE OF WORK Instructions to offerors: See page 1 block 8 for solicitation due date. Late offers will not be considered. SCOPE OF WORK: 1. SCOPE Provide Two (2) identical multi-turn actuators to be installed by others as replacements for existing gate hoist drives. Existing equipment is described on the drawings included with this solicitation. Actuators shall be designed and built in accordance with AWWA C542-09: Electric Motor Actuators for Valves and Slide Gates. 2. REQUIRED ACTUATOR PERFORMANCE POWER SUPPLY: Main is 480/277 volts AC, 3-phase, operators are powered by a 70-amp circuit breaker PF2 in Panelboard PDP1. Power to all of the gate operator enclosure heaters is supplied from a 20-amp breaker PGOH in Panelboard LRP. MINIMUM BREAK TORQUE (FT-LB) 6000 MAXIMUM TORQUE (FT-LB) 10000 TURNS TO OPEN 4.5 MINIMUM OUTPUT SPEED (RPM) 0.35 MINIMUM DUTY CYCLE AT BREAK TORQUE (SEC) 810 3. RECCOMENDED SITE VISIT INSPECTION OF EXISTING ACTUATORS Replacement actuators shall physically match existing actuators to the maximum extent to allow installation without modification to any other existing equipment. No modifications to existing hoist components will be allowed. Replacement actuator junction box, control panel, and hand wheel shall be in the same location and orientation and as the existing actuators. Replacement actuators shall have same mount bolt pattern and same output shaft dimensions and rotation direction as existing actuators. Replacement actuators shall be furnished complete with installation instructions and every part needed to complete the installations. The existing hoists are located at the Cross Lake Recreation Area, Crosslake, MN. The contractor is recommended to visit the site to inspect the existing actuators to obtain required measurements and layout information. Site visits to inspect the existing condition can be arranged and scheduled by contacting: U.S. ARMY CORPS OF ENGINEERS CROSS LAKE RECREATION AREA 35507 COUNTY ROAD 66, BOX 36 CROSSLAKE, MN 56442-0036 651-290-5793 4. ACTUATOR ENCLOSURES Furnish NEMA 4 cast iron or cast aluminum actuator enclosures for service in unprotected outdoors operating temperature range from -20 F to 150 F. All external fasteners shall be stainless steel. Provide space heaters inside enclosures wired same as existing heaters. Provide local control open/close/stop illuminated pushbutton station integral to enclosure. The control pushbutton station shall be configured so that quote mark open quote mark corresponds to gate raise and quote mark close quote mark corresponds to gate close as installed. Remote control operation and indication capability is not required. 5. ACTUATOR MOTORS AND GEARS Actuator shall not use a lost motion device to obtain required performance. Provide TENV 208 volt, single phase, capacitor start squirrel-cage induction motor, with NEMA MG1Class F insulation, and at least two Class B thermal contacts embedded within motor windings. All gears shall be enclosed. Shafts shall be mounted on antifriction bearings. Actuators shall be equipped with self-locking worm drives so to hold the gate load static at any manually selected shutoff position when the hoist is de-energized. Motor connection shall be by plug and socket and motor removal shall be possible without loss of lubricant. 6. ACTUATOR LIMIT SWITCHES Provide two independently adjustable position limit switches to serve as stop limiting devices for gate up and gate down positions. Motor shall include torque switches to de-energize the motor and prevent damage to the motor in the event of a stall condition. Limit switch contact rating rated 600 volts per ICS-125.6. 7. ACTUATOR HANDWHEEL AND CLUTCH Equip actuator with manual two-position clutch to select motor drive or hand wheel drive. Include external clutch handle with provision to padlock clutch handle in either position and to prevent unauthorized operation. Clutch shall prevent simultaneous engagement of motor and handwheel. The clutch system design shall provide that no damage results if hand operation is selected while the actuator is running. The clutch system design shall provide that no damage results if the actuator motor is started when hand operation is selected. The handwheel shall include an embossed / raised arrow to indicate gate open direction. 8. SUBMITTAL REQUIRED WITH BID All submittal information shall be in pdf format. Submit with the bid the make and model number of the actuator complete with dimensioned outline drawings and performance data. Submittal shall be sufficiently detailed to verify compliance with the specified actuator performance and layout criteria. 9. SUBMITTALS AFTER CONTRACT AWARD All submittal information shall be in pdf format. MODEL AND DESIGN DATA SUBMITTAL. For each actuator furnish complete job sheet including model number, purchase order, serial number, options, and point of contact for service and parts. Provide information required by Par. 4.2 of AWWA C542. For each actuator provide Certification and copy of both Proof-of-Design Test and Performance Test as defined by AWWA C542. OPERATION AND MAINTENANCE INFORMATION SUBMITTAL. Provide manufacturers standard package of instructions and information exploded view with parts list plus specified installation instructions. Include disassembly and troubleshooting instructions with exploded view of actuator components and itemized list of replacement parts. Include wiring diagrams, and limit switch and torque switch setting instructions. Include unit weight, hoisting instructions, and installation instructions. SHOP DRAWING SUBMITTAL. Provide manufacturers standard dimensioned outline drawing. In addition, provide detail drawings to completely describe the mount interface between the new actuator and the existing hoist gear reducer. Include fully dimensioned drawings of actuator mount including bolt pattern, output shaft, and coupling. WIRING DIAGRAM SUBMITTAL. Include manufacturer's standard wiring diagrams. Include job-specific wiring instructions to identify individual existing actuator conductors and locations, modifications to these conductors, and new locations in the new actuators. Wiring instructions shall include images of both existing actuator junction terminals and new actuator junction terminals with arrows, callouts, conductor identifications, and other information to aid field installation. INSTALLATION PARTS SUBMITTAL. For each actuator, provide all electric conduit, fittings, enclosures, and preassembled wire harnesses as required to complete the electrical installation. For each actuator, provide fully machined output drive coupling, keys, mount bolts, gaskets, and all required fasteners that are required to complete installation. 10.
